Very cute game! Could easily be expanded with new rulesets, fake dice, and extra challenges!
I'd also recommend adding a timer for how long the shift lasts and maybe adding a time bonus for handling customers quickly (while correctly). I wish there was a notification when you missed a cheater and with a reason why, because I did miss some people but I wasn't sure who I missed
Side note for Sen: Is that "Adult" Vincent Adultman from Bojack Horseman? If so, lovely reference!
